Tippmann 98c, SubZero X Chamber, RT, HyperStar Bolt, Remote, Armson Steath or BOA Express (depending on the day)
Marballizers, PMI Premium, although just about every paint I have used so far has been alright. Marbs and Premium are just the two best I have used so far.
My accuracy is actually better with this than with the stealth and it is a thousand times easier to clean too. The only paint that I have had ball breaks with is some really crappy economy paint that I bought one weekend because I was running low on cash. The cool thing is that after the ball break you just have to dry fire a few times and the barrel is back to shooting straight.
It is a little shiny. Makes it a little noticeable on the field when you are trying to hide in bushes and brush... but if they are close enough to spot the barrel then they are close enough for you to paint thier a$$.
This barrel is extremely accurate. Any ball breaks (rare) that you do experience are quickly fixed by a few dry fires. It is a work horse that you don't have to worry about when the paint starts flying.
